With the Lmu24 you have a variable speed compressor i wouldn't suggest attacking this repair on you own, get a Nate certified Sr. service tech out there and have them do cause your taking about high end cutting edge compressor technology, how ever if you need them i can email you a pdf copy of both owners and service manual.

The 48 before the VKD in the model number stands for 48000, BTU. For refrigeration, 1 Ton = 12000 BTU. Therefore 48000 BTU / 12000 (1 Ton) = 4 Tons

I have a Maytag window unit and i am trying to find out how many btu is has. right now it is in a small room and i want to know if it will work in a bigger size room. MODEL M6Q1OF2A SERIAL CR 264327...


that is a 10000 btu unit and a good rule of thumb to go by when 'sizing' a unit is 12000 btu for every 600 sq ft of cooling space (if the place is well insulated) or 400 sq ft (if not well insulated).
So, you have a 10000 btu unit which is 5/6th of 12000 btu - so - can reasonably expect that unit to cool approximately 500 sq feet.
In other words the room it's in now could be only - say - 300 sq feet (and well insulated) - in which case the AC unit is cooling it - well.
However, if you try to cool a 800 sq ft room - it will not work as well.
Hope this has helped.

My landlord installed this brand new out of the box. Our apt is 900 sq ft tops. This unit can't even cool down our living room and kitchen. If the whole 2 bedroom apt is 900 sq ft, you can imagine how...


The AC your landlord installed is rated at 8000 btu which is way too small for 900 sq ft. You need at least a 15000 Btu Air conditioner and a 'well insulated' house to be cool.
A good rule of thumb in the AC business says you need 1 ton (12000 btu) of Air conditioning for every 600 sq feet (if the house is well insulated) - if not - then you will need 1 ton (12000 btu) for every 400 sq feet.
So, if you have 900 sq feet and the house is well insulated you should have at least a 15000 btu unit.
If it's not well insulated you will need 24,000 btu.

The unit is not cooling the room. It is only comforting when you are in direct line of it.


you need to find out the size of the unit.
Rule of thumb - for every 600 sq ft of cooling area (in a well insulated house) you will need 1 ton of air conditioning. 1 ton = 12000 btu.
So, if your cooling area is 600 sq ft you would need an AC which was rated at 12000 btu, assuming your house is well insulated.
If it is not insulated well - you might need a bigger unit, i.e. 15000 btu.

Soleus 14000 btu air 12000 btu heat


Hi
Your text "will not blow out" indicates lack of air flow.
There are two posiblilities:
The upper blower wheel has failed (evaporator coil) OR the lower blower wheel has disintegrated (condenser coil in cooling mode) - which is very common on this Soleus Air model. The blower motors are very good and rarely fail.
Unplug from outlet, remove the six phillips head screws which secure the back to front of the appliance. Look for many broken pieces of your blower wheel.The proceed to www.soleusparts.com and order a blower wheel replacement kit(s).
Problem solved!

Mr slim unit in bedroom 9kbtu - room 11x12'- is humid, awful


Lets clarify. DRY mode only dehumidifes that air and does not cool. Cool is used for cooling. Dry mode doesn't normally have temp control; it is automatically set by the unit. I think 9000btu is a big unit for the room; it is overkill. I would switch to a 5000btu unit. it cannot be fixed and the BR unit needs to be uninstalled and the new unit needs to be re-installed. The price of commisioning, de-commisioning and new unit is something in which you will have to pay.
I take the time to answer your questions, so please rate me.
Thankyou

A/c cooling fine but not heating


The fan generally does not come on until the unit has achieved some high head pressure so that it can produce hot air. If it is low on gas it will not get to this stage.
